- Аннотация: Photosynthetic cyanobacteria, with their hyper-ability to assimilate nitrogen and phosphorus, offer a sustainable solution to managing the untreated discharge of swine wastewater. However, inconsistent nutrient recovery and laborious harvesting result in lower biomass production, hindering its widespread applications. To overcome these challenges, this study introduced a novel integrated approach combining corncob-based immobilization of Desertifilum tharense BERC-3 with a starvation-feast cultivation strategy, enabling rapid and highly efficient nutrient removal as well as high biomass production. By applying optimized 80 % nitrogen and phosphorus starvation in the presence of low-cost fibre hydrolysate supplementation, D. tharense BERC-3 produced 5.48 g L−1 biomass with 84.1 % nitrogen and 81.64 % phosphorus removal efficiencies within 3 days after entering the feast stage. Multi-omics analyses revealed mechanistic insights, where the metagenomic profile highlighted a 3-fold enrichment of beneficial bacteria (Alphaproteobacteria, Bacteroides) linked to enhanced nutrient cycling, and metabolomics uncovered adaptive metabolic strategies, such as polyhydroxybutyrate (PHB) accumulation during starvation and mobilization during feast phase. Overall, this approach enhanced nutrient removal efficiency and biomass production while advancing sustainable wastewater management and resource recovery.
